About

As a Senior ETL Developer at BEC Financial Technologies, I have extensive experience in the Business Intelligence field. My daily tasks include designing Data Vault models, creating mappings in Informatica, and loading data into Netezza and SQL Server. I have developed strong skills in reporting with Qlikview, Power BI, and SharePoint, making me proficient in data representation. My background in planning and monitoring high-budget projects, along with my ability to elicit project requirements and transform business needs into IT solutions, has been enhanced through my experience working with diverse teams. This exposure has given me the opportunity to connect with people of different mentalities and working styles, further enriching my problem-solving abilities in the IT field. In my previous roles, I have worked as an Oracle/ETL Developer at Credit Suisse, where I designed mappings in Informatica, automated tasks using Unix scripts, and designed Power BI dashboards while monitoring EC2 instances on AWS. At Roche, I focused on creating and modifying ETL processes in Informatica and designing DDLs in Teradata. My experience at Volvo Group involved performing ETL processes using SSIS Packages, writing queries in MS SQL and Netezza, and modifying reports using Power BI, Qlikview, and SharePoint. My educational background includes a Master of Computer Applications from Wroclaw University of Science and Technology, a Master's degree in Information Technology from Halmstad University, and a Bachelor of Engineering in Electrical, Electronics, and Communications Engineering from GTU.

Best back-end engineers I've ever worked with...​

“I interviewed about a dozen different firms. DevsData LLC is truly exceptional – their backend developers are some of the best I’ve ever worked with. I’ve worked with a lot of very well-qualified developers, locally in San Francisco, and remotely, so that is not a compliment I offer lightly. I appreciate their depth of knowledge and their ability to get things done quickly. “
